Long-range radionuclide transport in the atmosphere and water bodies

A long-range atmosphere transfer of radionuclides from nuclear explosions and nuclear plant accidents is considered. Data on radionuclide transport in the Yenisey, Pripet, Sozh, Iput’, and Besed’ rivers are presented. The time of the radionuclide transport from the Irish Sea to the Baltic and Barents seas is defined using changes in the cesium 134/cesium 137 isotope ratio.
